P-146: Fertility and Flow Cytometric Evaluations of Frozen-Thawed Rooster Semen in Cryopreservation Medium Containing Low Density Lipoprotein
Background: Frozen-thawed rooster semen is not reliable for use in artificial insemination in commercial stocks. Low density lipoprotein (LDL) has been assessed for effectiveness as a cryoprotectant in the extender to improve the quality of frozen-thawed rooster semen. Although LDL has been evaluated in a few studies in other species for semen cryopreservation, to date, no study has been conduc...
متن کاملEffect of selection for fertility of frozen-thawed semen in chickens on the fertility of fresh and stored semen.
Studies were conducted using 68 males from the seventh generation of a line of meat-type breeder chickens selected for increased duration of fertility of frozen-thawed semen and 69 males of the randomly selected control line. These chickens were used to determine the presence or absence of differences between the selected and control lines with respect to fertility and spermatozoal motility whe...
متن کاملCervical insemination of indigenous does with frozen-thawed goat semen during the non-breeding season
Introduction We received a request from the owner of a communal flock of indigenous goats in the Northern Province to inseminate some of his does with Gorno Altai semen. The only income he derived from this flock was through the sale of live goats at Christmas. He wanted to embark on a cross-breeding programme in an attempt to create an additional source of income from the fibre that would pote...
متن کاملCryopreservation of South African indigenous goat semen
The aim of this study was to cryopreserve and evaluate frozen-thawed semen parameters. Electroejaculator was used to collect semen from six bucks. Semen samples were divided into two parts. In one part, seminal plasma was removed and was not in the other one. Both semen sample parts were extended with egg-yolk Tris extender. Semen was thereafter cryopreserved in straws using liquid nitrogen. Da...
متن کاملFertility of frozen-thawed stallion semen cannot be predicted by the currently used laboratory methods
The aim of the project was to use current simple and practical laboratory tests and compare results with the foaling rates of mares inseminated with commercially produced frozen semen. In Exp. 1, semen was tested from 27 and in Exp. 2 from 23 stallions; 19 stallions participated in both experiments. The mean number of mares per stallion in both experiments was 37 (min. 7, max. 121). Sperm morph...
